In the experiments with zebrafish embryos, when this PAPC is not excluded, the cells do not move to the appropriate location, preventing the notochord from elongating to its proper length.

These fluorescent images of live zebrafish embryos show the movement, assembly and growth of cartilage-forming cells at 48, 72 and 96 hours post fertilization. Credit: 2023 Liu et al.

Critically, zebrafish embryos are also mostly transparent and — unlike those of, say, mice — develop outside the mother, making it possible for scientists to observe their early growth in ...

The second provides data on which genes were active in more than 120,000 zebrafish cells at 10 separate time points during the embryos’ first 10 days. “… we combine light-sheet microscopy ...

These tiny, 2-5 centimeter freshwater fish grow very quickly, developing as much in a day as a human embryo would in a month. "Zebrafish embryos are transparent and grow outside the mother, so we ...

The embryo of a wild type zebrafish above the embryo of banp mutant zebrafish, both four days post fertilization (dpf). The mutant embryo has smaller eyes compared to the wild type (shown with the ...

After clinical death, some of your cells refuse to quit, or even attempt to reconfigure into strange, emergent forms.

Steroid estrogens play an important role as embryos develop a sense of smell, new research shows. The study, which examined zebrafish embryos, discovered a type of astrocyte glial cell that is new ...

Developing zebrafish offer a convenient model for studying the heart because they are transparent, grow quickly—developing a heartbeat in only 24 hours—and can be imaged by the dozen.

Axolotls, zebrafish and hydra — freshwater polyps —can regrow entire body parts including their head, limbs, heart, brain and lungs after an injury. Humans, on the other hand, cannot.

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other ...
